Re: Sheared off bolt
 

I too am confused why removing the other stud will not allow the housing to slip off the broken stud, but if the case

Lay a washer on the housing, welding through the hole in the washer to bolt. Then weld a nut onto the washer and gently work it out.

Sheared off bolt

I was expecting the 'stat housing coming off was a given and the problem was dealing w/ the protruding broken bolt left behind?

Re: Sheared off bolt
 

Maybe I'm confused, but isn't the broken bolt &quot;time-welded&quot; to the housing?

Re: Sheared off bolt
 

I would think if you heated the T stat housing it would come off..

Yes.....the bolt is steel and the T-stat housing is aluminum whichhave become corroded together as they are dissimilar metals.

As stated above, heat and some sort of penetrating oil will work.

Why not center punch in the middle of the broken bolt and drill it out starting with a 1/8&quot; bit and working your way up until the wall thickness of the remnant is thin enough to either break off or break free from the housing?

It's a tedious, pain in the ass job but I've done it more times than I can count and it works.
